DIY Tuning
Has anyone tried to do a tune themselves? Or had any luck? I ordered the OBDI LT1 Tuning kit from Tunercats and was going to give it a shot. Got a few books on the subject, not an expert my any means but not new to the automotive world either.
My 94' is not a wild build, the link to my build is below, but enough to make it not run very smooth. Lt4 Hot cam, 1:6 rockers, shorty headers and recently a SLP induction setup.
Thanks for any insight. I may be biting off more than I can chew.
I also ordered the tips from http://lt1pcmtuning.com/tips/

I am just getting into tuning also and not quite sure what I am doing so this is the blind leading the blind to offer some help, but:
I have been looking at a few sites and found one that has a LT4 cammed bin file.
http://www.bfranker.badz28.com/LT1Edit/LT1files.htm
I thought the LT4 cammed bin file (referenced as "Professionally Tuned - Stock heads, LT4 HOT cam.) might get you close.
Although this is a .LT1.zip file it can be renamed to a dos filename (8 character . 3 character) name so that the following program can recognize it and convert it to a bin file.
This is a LT1 file but can be converted to a bin file using a link to a conversion program.

I also found another site that looks interesting.
http://fbodytech.com/
He has most of the stock bin files for LT1's in all the body styles and years.
He also has an xdf file that looks to be "hacked" to make the parameter names easier to understand, and quite a bit of other stuff.
Good luck.
